Using BIM technology for digital management of building construction is a key direction for improving project management efficiency and quality.

[0003] Existing BIM-based construction management systems simulate the building construction process using digital models and identify conflicts during construction through clash detection to determine the most suitable construction method. However, the process of simulating building construction requires multiple simulations to achieve the least or no-conflict construction method, which increases the workload and reduces the efficiency of obtaining the construction method.

[0006] Furthermore, the construction management platform also includes a risk warning module, which is configured to identify risk points of the building and mark risks in the virtual building model based on the risk points.

[0007] Furthermore, after marking the risk points in the virtual building model, the risk warning module also obtains the storage location of the construction strategy of the risk points and establishes a link to the construction strategy of the risk points based on the storage location.

[0008] Furthermore, the construction strategy module is also configured to acquire the construction quality standards of the building, generate a construction process model of the building based on the construction quality standards and the virtual building model, and store it. The construction terminal is configured to receive process query information from users and send process query instructions to the construction management platform based on the process query information; and The information interaction module is also configured to obtain the process quality standards and construction process model according to the process query command and send them to the construction terminal.

[0009] Furthermore, the construction management platform also includes a production perception module, which is configured to acquire the actual construction resources of the construction process segment, and the construction strategy module is also configured to acquire and store the optimized construction resources of each construction process segment. The construction terminal is configured to receive resource query information from users and send resource query instructions to the construction management platform based on the resource query information; and The information interaction module is also configured to obtain the target construction flow segment according to the resource query instruction, query the actual construction resources and optimized construction resources of the construction flow segment, and send them to the construction terminal.

[0010] Furthermore, the production perception module is also configured to acquire the actual construction progress of the building, and the construction strategy module is also configured to acquire and store the construction progress plan for each construction sequence segment. The construction terminal is configured to receive user progress query information and send resource query instructions to the construction management platform based on the progress query information; and The information interaction module is also configured to obtain the target construction sequence according to the progress query instruction, query the actual construction progress and construction progress plan of the construction sequence, and send them to the construction terminal.

[0011] Furthermore, the model building module is also configured to, if a revised drawing is received, conduct a joint review of the revised drawing and record the review information; and after the revised drawing passes the joint review, modify the virtual building model according to the revised drawing and record the modification information.

[0012] Furthermore, the model building module is also configured to identify complex nodes of the building, build a three-dimensional visual model of the complex nodes, and store it.

Then, through a construction strategy module, an optimization algorithm based on big data is used to obtain an optimized construction strategy for each construction flow section. Finally, each optimized construction strategy is used to label the corresponding flow section model for user querying. Because the construction strategy module in this invention uses a big data-based optimization algorithm to obtain the optimized construction strategy for each construction flow section, compared with the existing technology that relies on multiple simulation attempts, the workload of obtaining the optimized construction strategy for each construction flow section can be reduced, thereby improving work efficiency.

[0019] Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of a construction site intelligent construction management system based on BIM technology, according to an embodiment of the present invention. This system is used to intelligently manage the construction process of a building in order to improve the reliability of building construction.

[0020] exist Figure 1In the structure shown, the construction management system in this embodiment includes a construction management platform 10 and multiple construction terminals 20. The construction management platform 10 can be a workstation, a host computer, or a cloud server. The construction terminals 20 can be mobile terminal devices such as mobile phones or tablets. Each construction terminal 20 is connected to the construction management platform 10 and is equipped with an application for information interaction with the construction management platform 10. Users can access the construction management platform 10 through the application on the construction terminal 20.

[0021] The construction management platform 10 in this embodiment includes a model building module 11, a construction segmentation module 12, a construction strategy module 13, and an information interaction module 14. The construction management platform 10 is equipped with a data interaction interface and a human-computer interaction device. The data interaction interface can be a USB interface, and the human-computer interaction device can include a mouse, keyboard, and monitor, or a touchscreen. Users can use the human-computer interaction device to draw construction drawings of buildings using the drafting software installed on the construction management platform 10, and can also read construction drawings of buildings from external storage devices through the data interaction interface.

[0022] The model building module 11 is used to acquire the building's construction drawings and, using BIM technology, construct a virtual building model of the building based on these drawings. The construction segmentation module 12 is used to acquire the building's construction flow segments and map these segments onto the virtual construction model to obtain a flow segment model corresponding to each construction flow segment. The construction strategy module 13 is used to acquire optimized construction strategies for each construction flow segment using a big data-based optimization algorithm, and then annotates and stores the corresponding flow segment models according to these optimized strategies. The information interaction module 14 is used to interact with the construction terminal 20 to provide users with building construction query services.

[0023] In this embodiment, the method of the model building module 11 to construct a virtual building model using BIM technology includes: using 3D design software to construct a 3D model of the building based on the building's construction drawings.

[0024] In this embodiment, BIM-based 3D design software (such as Revit, ArchiCAD, or Civil 3D software) can be used to reconstruct the complete geometric shape and spatial relationships of the building based on the set information, dimension annotations, and construction details in the building's construction drawings, so as to obtain a 3D model of the building, and use this 3D model as a virtual building model of the building.

[0025] In this embodiment, during the construction of a building, the building can be divided into multiple independent construction areas in plan or space. Each construction area corresponds to a construction flow section. By rationally arranging the construction sequence and time of each construction flow section, efficient collaborative operation of multiple processes and trades can be achieved during the building construction process.

[0026] In this embodiment, the user can divide the construction flow into sections according to the structure and distribution of the building, and input the division results into the construction management platform 10. The construction segmentation module 12 can map each construction flow into the building model according to the construction flow division results and the building part corresponding to each construction flow, and use the three-dimensional model of the building part corresponding to each construction flow as the flow model corresponding to each construction flow.

[0027] In this embodiment, taking one construction sequence as an example, the construction strategy module 13 obtains the optimized construction strategy for that construction sequence as follows: Figure 3 As shown, it includes the following steps: Step S101: Obtain the shape, size, and preset construction strategy of multiple preset flow sections; Step S102: Calculate the similarity between the constructed flow segment and each preset flow segment based on the shape and size of the constructed flow segment, and take the preset flow segment with the highest similarity to the constructed flow segment as the reference flow segment; Step S103: Based on the preset construction strategy of the reference flow section, the virtual building model of the building is simulated for construction, and conflicts and interferences in the simulated construction process are eliminated to obtain the optimized construction strategy for the construction flow section.

[0028] In this embodiment, taking one of the preset flow segments as an example, the shape similarity between the constructed flow segment and the preset flow segment can be calculated based on the shape of the constructed flow segment and the shape of the preset flow segment. The size similarity between the constructed flow segment and the preset flow segment can be calculated based on the size of the constructed flow segment and the size of the preset flow segment.

[0029] Assuming the shape similarity between the constructed water flow segment and the preset water flow segment is S1, the methods for obtaining the shape similarity S1 include: First, randomly select n feature points from the construction flow section and obtain the building structure within a set range around each feature point; Then, matching points that match the feature points within the preset flow segment are identified. That is, if the surrounding building structure of a location within the preset flow segment is identical to the surrounding building structure of one of the feature points, then that location is determined to be a matching point. Let the number of matching points in the preset flow segment be m. Assuming the volume of the constructed flow section is V1, the volume of the preset flow section is V2, and the dimensional similarity between the dimensions of the constructed flow section and the dimensions of the preset flow section is S2, then... Let Sim be the similarity between the pre-designed flow section and the constructed flow section. Where α is the shape similarity weight and β is the size similarity weight.

[0030] The working principle of the BIM-based smart construction of the construction site in this embodiment includes: Users can input construction query information on the construction terminal 20. The construction query information includes at least the construction process section to be queried. After receiving the construction query information, the construction terminal 20 generates a construction query instruction based on the construction query information and sends it to the construction management platform 10.

[0031] After receiving a construction query instruction from the construction terminal 20, the construction management platform 10 obtains the construction flow segment corresponding to the construction query instruction, obtains the flow segment model and its construction strategy annotation information corresponding to the construction flow segment, and sends them to the construction terminal 20; after receiving the flow segment model and its construction strategy information, the construction terminal equipment 20 displays the flow segment model and construction strategy information on the display screen.

[0032] As described above, in this embodiment, after constructing a virtual building model of the building using the model building module, construction flow segments are mapped onto the virtual building model to obtain a flow segment model corresponding to each construction flow segment. Then, through the construction strategy module, an optimization algorithm based on big data is used to obtain an optimized construction strategy for each construction flow segment. Finally, each optimized construction strategy is used to label the corresponding flow segment model for user querying. Because the construction strategy module in this embodiment uses an optimization algorithm based on big data to obtain the optimized construction strategy for each construction flow segment, compared with the existing method of multiple simulation attempts, the workload of obtaining the optimized construction strategy for each construction flow segment can be reduced, thereby improving work efficiency.

[0033] In some embodiments of the present invention, the construction management platform 10 further includes a risk warning module 15, which is used to identify risk points in the building and to mark the virtual building model with risk based on the risk points.

[0034] In this embodiment, the risk points in the building include technical risk points, quality risk points, and safety risk points. Users can mark these risk points on the building drawings during the construction process. The risk warning module 15 identifies the location of these risk points by analyzing the user-marked areas on the drawings and adds corresponding risk annotations to the virtual building model. Alternatively, the risk warning module 15 can first obtain a preset risk structure, then identify the location on the virtual building model to match the preset risk structure, and then add risk annotations to that location.

[0035] In this embodiment, risk points are marked in the virtual building model of the building. During the construction process, users can view these risk points and take safety measures to improve the safety of the building.

[0036] Furthermore, the risk warning module 15 also acquires and stores the construction strategy corresponding to each risk point, and after marking the virtual building model for risks, establishes a construction strategy link for each risk point according to the storage location of each construction strategy.

[0037] In this embodiment, the risk warning module 15 can pre-store construction measures for multiple preset risk structures and obtain the storage address of the construction measures; after identifying and marking risk points in the virtual building model, a link is established between each risk point and the storage address of its corresponding construction measure.

[0038] In this embodiment, all risk points marked in the building model are linked to construction strategies. Users can view solutions for the risk points through these links, thus ensuring the reliability of the construction references provided.

[0039] In some embodiments of the present invention, the construction strategy module 13 is further configured to acquire the construction quality standards of the building, generate a construction process model of the building based on the construction quality standards and the virtual building model, and store it.

[0040] For example, a layout process model can be generated based on the construction layout process quality standards, and the basic information such as axis position and elevation, acceptance standards and quality control points can be reflected in the layout process model; a rebar binding process model can be generated based on the rebar binding process quality standards, and the basic information of rebar construction (such as anchorage, lap and hook length, etc.), quality acceptance standards and quality control points can be reflected in the rebar binding process model.

[0041] The construction terminal 20 acquires the user's process query information and sends a process query instruction to the construction management platform 10 according to the process query instruction. After receiving the process query instruction, the construction management platform 10 acquires the construction process model corresponding to the process query instruction and sends it to the construction terminal 20; after receiving the construction process model from the construction management platform 10, the construction terminal 20 displays the construction process model on the display screen for the user to view.

[0042] In this embodiment, the construction strategy module 13 of the construction management platform 10 can also generate a construction process model of the building. The construction terminal 20 can obtain the construction process model of the building from the construction management platform 10 and display it according to the user's process query information, so as to provide process reference for the user in the process of building construction and improve the reliability of construction reference.

[0043] In some embodiments of the present invention, the construction strategy module 13 is further configured to obtain optimized construction resources for each construction phase based on the optimized construction strategy for each construction phase. The construction management platform 10 is also equipped with a production sensing module 16, which is configured to obtain the actual construction resources for each construction phase and store these actual construction resources.

[0044] In this embodiment, if the construction terminal 20 receives a resource query request for a certain construction process segment input by a user, it takes that construction process segment as the target construction process segment, generates a resource query instruction for the target construction process segment, and sends it to the construction management platform 10. After receiving the resource query instruction from the construction terminal 20, the information interaction module 40 obtains the target construction process segment according to the resource query instruction, queries the actual construction resources and optimized construction resources of the target construction process segment from the stored data, and sends them to the construction terminal 20.

[0045] After receiving the actual construction resources and optimized construction resources of the target construction pipeline, the construction terminal 20 generates and displays a resource comparison map of the target construction pipeline based on the actual construction resources and optimized construction resources for the user to view.

[0046] In this embodiment, the construction strategy module 13 of the construction management platform 10 can also generate optimized construction resources for each construction flow segment of the building. The construction terminal 20 can obtain the optimized construction resources and actual construction resources of the construction flow segment corresponding to the resource query information from the construction management platform 10 and display them so that the user can check whether the optimized construction resources and actual construction resources of the target construction flow segment match, thereby improving the reliability of providing construction reference for the building.

[0047] In some embodiments of the present invention, the construction strategy module 13 is further configured to obtain and store the construction progress plan for each construction flow segment according to the optimized construction strategy for each construction flow segment, and the production perception module 16 is further configured to obtain and store the actual construction progress of the building.

[0048] In this embodiment, if the construction terminal 20 receives a progress query request for a certain construction phase from a user, it takes that construction phase as the target construction phase, generates a progress query instruction for the target construction phase, and sends it to the construction management platform 10. After receiving the progress query instruction from the construction terminal 20, the information interaction module 40 obtains the target construction phase according to the progress query instruction, queries the actual construction progress and construction progress plan of the target construction phase from the stored data, and sends it to the construction terminal 20.

[0049] After receiving the actual construction progress and construction progress plan of the target construction sequence, the construction terminal 20 generates and displays a progress comparison chart of the target construction sequence based on the actual construction progress and construction progress plan for the user to view.

[0050] In this embodiment, the construction strategy module 13 of the construction management platform 10 can also generate a construction progress plan for each construction phase of the building; the construction terminal 20 can obtain the construction progress plan and actual construction supervision of the construction phase corresponding to the resource query information from the construction management platform 10 according to the user's resource query information and display it so that the user can check whether the actual construction progress of the target construction phase conforms to its corresponding construction progress plan, thereby improving the reliability of providing construction reference for the building.

[0051] In some embodiments of the present invention, the model building module 11 is further configured to: if a revised drawing is received, to conduct a joint review of the revised drawing and record the review information; After the revised drawings are approved, the virtual building model is modified according to the revised drawings, and the modification information of the virtual building model is recorded.

[0052] In this embodiment, multiple reviewers can conduct a joint review of the revised drawings and record the review results of each reviewer; alternatively, drawing review rules can be pre-set, and the revised drawings can be reviewed according to the drawing review rules, and the review results can be recorded.

[0053] In this embodiment, after obtaining the revised drawings, the model building module 11 of the construction management platform 10 first reviews the revised drawings to ensure their legality and compliance, and to prevent unreasonable revised drawings from increasing the construction difficulty of the building. After the revised drawings have been reviewed, the virtual building model is modified according to the revised drawings, which can improve the flexibility of the virtual building model. Recording the changes to the virtual building model can provide a basis for viewing the changes to the virtual building model.

[0054] In some embodiments of the present invention, the model building module 11 is further configured to: identify complex nodes of a building and build a three-dimensional visual model of the complex node.

[0055] In this embodiment, the model building module 11 can obtain the user's annotations of complex nodes in the building, determine the location of complex nodes in the building based on the annotations, and then build a three-dimensional visual model of the building at that location separately. The building method is the same as the building method of the virtual building model, and the three-dimensional visual model is the three-dimensional visual model of the complex nodes in the building.

[0056] Users can input the complex node they want to view on the construction terminal 20. The construction terminal 20 then sends the node viewing information of the complex node to the construction management platform 10. After receiving the node viewing information, the information interaction module 14 of the construction management platform 10 obtains the target complex node based on the node viewing information, obtains the three-dimensional visual model of the target complex node, and sends it to the construction terminal 20. After receiving the three-dimensional visual model of the target complex node, the construction terminal 20 displays the three-dimensional visual model on the display screen for users to view.

[0057] This embodiment can identify complex nodes of a building, establish a three-dimensional visual model of the complex node, and after receiving a user's viewing request, obtain the three-dimensional visual model of the target complex node according to the viewing request and display it on the construction terminal 20, so that the user can observe the structure of the target complex node on the construction terminal 20, thereby improving the reliability of providing construction reference for the building.

[0058] In some embodiments of the present invention, the system further includes an authentication module 17 configured to perform user authentication and permission authentication.

[0059] In this embodiment, the administrator's identity information can be configured and stored during the system initialization process. Users with the identity of an administrator have the authority to manage user permissions.

[0060] Users can register and log in at the construction terminal 20. The user registration method includes: the user enters identity information, verification information, and registration request information in the application of the construction terminal 20. The verification information can be encrypted verification information such as a password, or physiological verification information such as facial recognition or fingerprint. The construction terminal 20 sends the user's identity information, verification information, and registration request information to the construction management platform 10. After receiving the user's identity information, verification information, and registration request information, the construction management platform 10 obtains the user's permission information through the administrator's permission settings and stores the user's identity information and permission information in the database.

[0061] The method for users to log in on the construction terminal 20 includes: the user enters identity information, verification information, and login request information in the application of the construction terminal 20; the construction terminal 20 sends the user's identity information, verification information, and login request information to the construction management platform 10; the identity verification module 17 reads the stored verification information from the database based on the user's identity information and determines whether the verification information received from the construction terminal 20 is consistent with the verification information read from the database; if they are inconsistent, the information interaction module 14 sends a message to the construction terminal 20 to refuse the user's login; if they are consistent, the information interaction module 14 sends a message to the construction terminal 20 to allow the user to log in, obtains the user's permission information based on the user's identity information, and restricts the user's usage functions based on the permission information.

[0062] In this embodiment, an authentication module 17 is set on the construction management platform 10, and the authentication module 17 is used for authentication and permission management, which can improve the security of the construction management system.

[0063] In some embodiments of the present invention, the information interaction module 14 is further configured to generate push information according to a preset push rule and send the push information to all construction terminals 20.

[0064] In this embodiment, the information interaction module 14 can determine which information belongs to the push information according to the preset push rules. For example, it can obtain the remaining construction time of each construction section according to the construction progress plan. If the remaining construction time is less than the set time, the construction period reminder information is used as the push information; or, if the construction drawings change, push information on the drawing changes is generated.

[0065] After receiving the push information, the information interaction module 14 sends the push information to the construction terminal 20; after receiving the push information from the system, the information interaction module 14 issues a push notification voice and displays a brief introduction of the push information; if it detects that the user's operation is to view the push information, it displays the push information for the user to view.

[0066] In this embodiment, the information interaction module 14 of the construction management platform 10 also has an information push function, which can push information to users and send notifications to users in a timely manner, thereby improving the timeliness of information reminders from the construction management system.

[0067] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
